NETWORK HOST STATUS
This RFC reports on the status of most Network Hosts from May 22 to
June 2.
No testing was done on Memorial Day, which Massachusetts celebrated
on May 29. No testing was done on May 31 and June 1 due to an
attempt to install the new IMP system.
Three new terminal IMPs were installed during this interval. On June
1, Terminal IMP #155 was installed at Fort Belvoir in Fairfax,
Virginia; on June 3, Terminal IMP #154 was installed at SAAC (Seismic
Array Analysis Center) in Alexandria, Virginia; and on June 5,
Terminal IMP #153 was installed at NOAA (National Oceanic Analysis
Agency) in Boulder, Colorado.
Several Hosts are currently excluded from the daily testing. These
Hosts fall into two categories:
1) Hosts which are not expected to be functioning on the Network as
servers (available for use from other sites) on a regular basis
for at least two weeks. The only Host in this category is the
PDP-10 at Case (Network address 13).
2) Hosts which are currently intended to be users only. Included
here are the Terminal IMPs, which are presently in the Network
(AMES, MITRE, NBS, ETAC, USC, GWC, NOAA, SAAC, BELVOIR, and
BBN*). This category also includes the Network Control Center
___________
*The BBN Terminal IMP (Network Address 158) is a prototype and as
such is frequently not connected to the Network, but being used
to refine and debug the Terminal IMP programs.

computer (Network address 5) which is used solely for gathering
statistics from the Network. Finally, included among these Hosts are
the following:

7 Rand IBM-360/65
73 Harvard PDP-1
12 Illinois PDP-11
19 NBS PDP-11
23 USC IBM-360/44
The tables on the next two pages summarize the Host status for this
period.
